Why can't the police live in the traffic police dormitory?

Because we live in dormitories according to the needs of duty, the traffic team provides dormitories for the auxiliary police. However, according to personal wishes, it is not mandatory to live in a dormitory, but you can still go home and live near your home. However, the transportation team should have staff on duty 24 hours a day, so it is more convenient to choose a dormitory. The traffic police work very hard and belong to continuous rotation.
